This mod expands Caldera Mine in every way possible. New quests (Including a Great House quest for all three Great Houses), new NPCs, new side quests, an expanded exterior and interior, and overall a completely lore-friendly revamp of Caldera Mine.

Dagoth Ur has been defeated, but the continued presence of the Sixth House still poses a threat to Morrowind. A lieutenant of the Tribe Unmourned has come out of the shadows in a sinister plot to resurrect Dagoth Ur. But hope is not lost, a new Spymaster for the Blades has arrived in Ebonheart, here to help the Nerevarine in his new struggle.

His methods are atypical, but an Argonian in the Sixth House base of Bensamsi has discovered a way to create soul gems from ash salts. Talk to Heem-La in the Ald-ruhn Guild of Mages about research opportunities if you would like to learn more.
